Set a saute pan over medium heat and add beef, onion, and peppers. Break the meat apart into small chunks and cook until the hamburger is browned and the onions are tender.
Add the garlic cloves and continue cooking another two minutes, until the garlic is fragrant.
Add all remaining ingredients into the pan and simmer for a few minutes to allow the flavors to combine.
Serve sloppy joe mixture in equal portions on hamburger buns.
Notes
Any leftover meat mixture can be refrigerated for up to a week and reheated as needed. Store in an airtight container.
